boot screen

Hey, this thread is an updated version. My previous thread had stated issues about many things but I have corrected most of them. Last of the issues are that there is no backlight but shows the desktop when light is flashed through the apple. I did find the fuse F9800 and found it to be faulty...

Radeon RX6800 16 GB is now the fastest card for Mac Pro 4,1/5,1 with standard EFI boot screen. You can see EFI boot screen even without any HDD/SSD installed at all. macOS Monterey 12.2.1 works natively without any patches. You just need to either move Monterey from supported Mac or install it...

Hi, I have got the old Mac Pro 4.1 (early 2009) with GTX 680. I get the display when it's past the boot but while in boot mode there is just nothing, black screen. So, the problem I am having is just clearly I've got to completely reinstall the mac OS and just because I can't see anything while...

Hi, My Mac Pro 5.1 has experienced a power outage, and after that I have been unable to boot it succesfully. I get to the Logo screen with the progress bar getting slowly to 100% and then it stays there. I have tried all shortcuts when booting, and I haven't even been able to get the Recovery...

Howdy all! This has probably been asked a number of times, but I cant seem to find a search result that inspires a lot of confidence for accurate information. At the risk of violating mac rumors policies, im asking if its possible to modify a vega 56 to show a boot screen, as is possible with...

I have a Mac Pro 5,1 that has been running great. Running Mojove 10.14.6 For about a year I've used a M.2 Evo 750 NVME in PCI slot 3 drive as my primary drive with my OS and its worked fine. I shut down my machine last night and when I booted it up this AM it would chime but nothing showed on...

Hi, I just bought a Mac Pro 5.1. Single Processor Xeon 2.8 Ghz and ATI Radeon HD 5770. The computer came with Snow Leopard installed so my next step was to begin the upgrade process to at least High Sierra until I buy a Metal compatible GPU. The problem I came up with was that I foolishly...

Let's say you've fixed up a classic Mac Pro, and it's going to a new home. You've installed a new GPU and upgraded the OS to Mojave, maybe preloaded some useful apps like Macs Fan Control, or given the NVMe boot drive a better looking Finder icon. You don't want to completely reinstall macOS...

New member here, with ... Basic question: I see the term "boot screen" a lot in reference to video cards, but can't seem to locate an explicit definition. Could someone explain: what exactly is meant by "boot screen" ? and, perhaps more importantly what are the effects and implications of...

Hi all. I have a mac pro 4,1 (flashed to 5,1) and am looking to beef up the GPU a little (and get mojave/metal compatibility). I know Windows cards can and do work out of the box in later OSX revisions with the caveat that the boot screen won't work. I use filevault and would like a boot screen...

Hello Community! I am experiencing a very strange issue. I did not even find anything similar on the web, though this does not necessarily mean anything ;) I managed to get an Mac Pro in original condition for a very convenient price. Mac Pro 4,1 - ATI 5770 - 16GB Ram... I did flash it to a...

I have a mid 2010 MacBook white unibody that is stuck on the boot screen. It would do this intermittently when I first upgraded to High Sierra, but not every time I reboot it stays stuck. It has 4gb RAM. I was needing suggestions for fixing this. I have heard some say upgrading the memory to...

I've been searching for hours and can't find a straight answer. Is it possible to flash an RX 580 to get the boot screen?

I have an ATI 5870 that was flashed so I got a boot screen. I've had it for probably three years running on my Mac Pro 3,1. A week or two ago I bought a 30" ACD to replace one of the two 23" ACDs I've been running on it, both displays being run off the DVI ports on the card. I have a third...

Just installed a GTX 760 into my Mac Pro. It works great. I am concerned about the absence of a boot screen because I have Windows 10 installed via bootcamp & will need to use it now & then for gaming. I don't want to find myself unable to boot into OS X. Is this avoidable just using the...

Hi again people, As you may be able to deduce from my recent posts I'm currently playing around a bit with my 2009 4,1 with 5,1 update. I have recently installed a flashed XFX 5770 and despite probs with known issues such as pci fan speed and display port output was pleased with how it was...

Hello, I have a 2010 Mac Pro with the stock ATI Radeon 5770. When I boot with a 20" DVI Cinema Display attached, everything works perfectly , I get drive selection if I boot holding option, and I can see the password field to disable FileVault 2. Where my issue arises is that my normal setup...

It's a recently refurbished MacBook Pro 15" from late 2011 I tried resetting the pram with shift+commmand+p+r while powering on. Same prohibitory sign. I tried command+r. Same. I tried command+shift+r for the online recovery. Nothing. I tried holding down shift while powering on to run safe...

Hey MR, I just got a 2012 quad-core Mac Pro. Absolutely love it. Big step up from a 2011 Mini. I have a new ASUS gtx 970 'strix' OC edition and wanted to know a couple things: 1. What are my options to flash EFI onto it, I have zero experience in this area. 2. Can I just keep the 5770 in and...
